I'd say that it looks like a good 4 foot depth from the bottom to the where it looks like the water was upto once, which is a fair depth for a canal, but I think you are right, as you can see a red seam which may be the clay, the rest is maybe compacted silt as it's broken off rather than just run like I would expect silt to do normally.
